To all whom it may concern:

Be it known that I, MILTON Wn'm, a citizen of the United States, and a resident of the c'ty of New York, borough of Manhatg tan, in the county and State of New York,

have invented a new and Improved Attachment for High-Speed Winders, of which the 3. following is a full, clear, and-exact description. a

pg ,Theinvention relates to-kuitting machincry for. knitting hosiery and like articles of raw silk.

The object of the invention is to provide a' new and improved attachment for high 315 speed winders arranged to permit of knitting hosiery and like articles of raw silk thread formed of a plurality of raw silk ends in doubled, untwisted relation, thus dispensing entirely with the operation of silk throwing or twisting.

In order to accomplish the desired result, use is made of a vertically disposed spindle adapted to carry a spool filled with a thread formed of doubled, untwisted raw silk ends, 25 said spindle, and an elastic-band held on the free end of the said flier arm and provided with a thread guide for the passage of the.

thread unwindin from the said spool.

A practical em odiment of the invention is represented in the accompanying drawings forming a art of this specificatlon, in .which similar aracters of reference ind1- cate corresponding arts in both vlews.

Figure 1 is a si e elevation of the improved high speed winder with parts shown in section; an

Fig. 2 is a sectional plan view of the same on the line 2-2-of Fi 1.

A. number of raw silk ends arranged one alongside the other form a. non-twisted thread unwinding from a spool 11 removably mounted on a vertically disposed s indle 12 fixed at its upper end to a suitalile overhead support 13 directly above the knitting machine. The bottom flange of the spool 11 rests on a key 14 plvoted at 15 to the spindle and adapted to swing nto alinement with the spindle whenever 1t 15 desired to remove an empty spool from the spindle 12 and place a filled spool on the spindle 12. It is understood that after the spool is slipped onto the spindle 12 the key 14 is swung into right-angled posltlon relative to the spindle 12 to support the spool elastic band 17 the ends a flexible flier arm mounted to swing on the i 11 on the spindle. The thread 10 after unwinding from the spool 11 passes through an eye or slmllar thread guide 16'l1eld onthe its upper end to an eye'18 of a flexible flier arm 19 terminating in acoil 20,-tlie end of which is fastened to an arm'21 of a hub 22 lower end of an elastic band 17 attached at shown in'the form of a'heavy coil of'wire loosely encircling the spindle 12 and resting on a collar 23 formed on the spindle a short distance above the top of the spool "11. v The thread 10 after leaving the eye 16' passes through a thread guide 25 locatedcentrally below the spindle 12 and abovea winding machine or a knitting machine to be formed into kmt interlocked stitches for producing a knit article in which the thread 10 is .formed of non-twisted raw silk ends. By

taking the untwisted thread 10 off the spool by way of the thread guide 16 held on the of the thread are not liable to become entangled. It is understood that when the thread 10 is passed to a windin machine it is wound up on a cone, cop, tu e, bobbin or similar spool packa e or device, to be subsequently used on t e knitting machine for delivering the thread to the thread carrier and the knitting elements of the knitting machine, but, as above stated, the thread 10 may be directly fed to the thread carrier of a hosiery or other knitting machine.

By using the elastic band 17 on the flexible flier arm 19 a very minute yielding is obtained by the resilienc of the said parts so that the raw silk end s of the thread 10 are not liable to become tangled up during the time the thread unwinds from the spool, and hence it is posible to directly feed the thread IO of untwisted raw silk ends directly into the-knitting machine to be knit into hosiery or a similar article with the raw silk. ends of the thread remaining in doubled, untwisted relation one relative to the other.

In practice it has been found that the elastic band in conjunction with the spring flier arm 19 gives the desired result as the elasticity of the elastic band together with its flexibility permits it to readily yield in a lengthwise as well as in an outward and inward direction according to the feeding pull exerted by the knitting machine or winder. As the flier arm and its elastic band are rendered exceedingly sensitive practi cally very little if any tension is put, on the thread 10 to permit the proper formation of the stitches in the knittmg machine.

The elastic band also takes care of any variation in the resistance offered by the spool to the unwinding thread as the spool on a low speed of the winder remains at a standstill but turns on an increase in the speed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1- 1. A high speed winder attachment,- comprising a spindle adapted to carry a spool filled with a thread formed of doubled untwisted raw silk ends, and a flexible flier arm mounted toswing on the said spindle and having a terminal mounted to swing on the free end of the said flier arm, the said terminal being provided with a thread guide for the passage of vthe thread unwinding from the said spool, the said terminalbeing capable of yielding in a lengthwise, an outward and an inward direction according to the pull exerted by the thread on thesaid thread-guide,

- 2. A high speed winder attachment, comprising a spindle adapted to carry a spool filled with a thread formed of doubled un-' twisted raw silk ends, a flexible flierarm having a hub mounted to swing on the spindle above the said spool, and an elastic hand held on the free end of the said flier arm and.

provided at its terminal with a thread guide for the passage of the thread unwinding from the said spool. v v

3. A high speed winder attachment, comprising a spindle adapted to carry a spool filled with a thread formedofdoubled 'untwisted raw silk ends, a flexible flier arm having a hub mounted to swing on the spindle above'the said spool, an elastic handheld on the free end of the said flier arm and provided at its terminal with'a thread guide for the passage of the thread unwinding from the said spool, anda thread guide dis posed centrally below'the said spmdle and through whidh passesthe thread after leaving the eye on the said elastic band.
